Accordingly, the plurality of parallel conductors are exposed to the outside at both end portions of the flat cable. Further, the connecting members are superimposed on one surface of the flat cable so that conductors of the flat cable cross the conductors of the connecting members. Then, the conductors of the connecting members, which are exposed to welding-connection holes, are connected to the conductors of the flat cable by welding (for example, see Japanese Unexamined Patent Application Publication No. 11-97088).

Accordingly, since the shape of a mold used to manufacture the connecting member becomes complicated, the manufacturing costs of the lead block are increased. For this reason, it is difficult to reduce the costs of the rotary connector.

  • the flat cable and the lead block overlap each other so that the plurality of pin terminals cross the plurality of belt-like conductors.
  • the plurality of pin terminals of the lead block are fitted to an insulating support member and held so that leading end portions of the plurality of pin terminals protrude to the outside, and include joint portions connected to the connecting portions of the flat cable.
  • the lead block since the lead block does not need to be formed using a complicated mold by insert molding and it is possible to form the lead block simply by fitting the plurality of pin terminals to the insulating support member and holding the plurality of pin terminals, it is possible to significantly reduce the costs of the lead block. Accordingly, it is possible to provide a rotary connector of which costs can be reduced.
